Supporting tools let the application inspect available avatars and voices, check progress and look up remaining credits.
The video is created in the user's existing HeyGen account and draws on that plan's credits, which the guide says carries no separate MCP pricing. This makes video generation a step that can follow work already happening in an assistant, such as preparing a script, without requiring the user to carry the brief into a separate video-creation session.
Key takeaways · AI-distilled
HeyGen ships one MCP server; any AI app that speaks the Model Context Protocol, including ChatGPT, Claude, and Cursor, can attach to it and get the same Video Agent that powers HeyGen's own web app.
There is no separate MCP pricing: video generation through the MCP draws credits from the user's existing HeyGen plan, the same pool the web app uses.
Instead of pasting a raw API key into a config file or chat, HeyGen's MCP requires a real login with scoped, revocable permission, so the connecting AI app never holds full account access.
The core tool is 'generate a video' from a plain-English brief; supporting tools let the AI app browse existing avatars and voices, check render status, and check remaining credits before a batch job.
